Luna is eleven years old and obsessed with adventure. While visiting the island of Newfoundland, Luna finally has a chance to explore a setting as big as her imagination, but her father, a roving journalist and widower, doesn’t want her straying too far. Ignoring his caution, Luna sets off on her own and enters a mysterious forest, where she bests a monster in a battle of wits—and unleashes a creeping darkness that devours her father. Now she must embark on a real quest: to heal the island, the ghosts that haunt it, and the people she cares about most.
